About G50

G50 is the ICD-10-CM diagnosis code for disorders of trigeminal nerve. It belongs to block G50-G59 (nerve, nerve root and plexus disorders) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: G50.0 (neuralgia), G50.1 (pain), G50.8 (nerve) and G50.9 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
